Lots of things such as phototransistor circuits, application, color sensor amplifier, operational amplifier, conversion circuit, photocurrent amplifier, and sensor are explained in the application note. The application note tells us information related to amplifiers, detecting circuit, optoelectronics photodiode, conversion, auto stroboscope circuit, and photocurrent amplifier circuit.
In this application note you can read information related to signal detection circuit, sensor amplifier circuit, characteristics, fundamental phototransistor circuits, output voltage, modulated signal, and intensity. These are grabbed from the application note:
Optoelectronics Application Note Photodiode/Phototransistor Application Circuit FUNDAMENTAL PHOTODIODE CIRCUITS Figures 1 and 2 show the fundamental photodiode circuits. The response time is inversely proportional to the reverse bias voltage and is expressed as follows: r = C j × RL In the circuit of Figure 4 (A), the output (VOUT ) is given as: VOUT = IP × R1 + IB × R1 + VBE 1 C j = A ( V D – V R ) – -n This arrangement provides a large output and relatively fast response.
Even more, the application note presents more things like stroboscope circuit, fundamental photodiode circuits, stroboscope, color sensor, modulated signal detection, and amplifier circuit.
